Rollback Plan
A documented and tested procedure for reverting a specific release gracefully.
Detailed Explanation
A Rollback Plan outlines the exact steps, scripts, and commands needed to undo a deployment. Crucially, it must address how to handle forward-migrated data and state changes. The best rollback plans are fully automated and verified before the deployment even begins.
Why It Matters
When production is down and adrenaline is high, engineers need a clear, tested playbook rather than trying to improvise a reverse-deployment under pressure.
Common Failure Mode
Practical Example
Production Manifestation
A runbook document, an automated 'revert' button in a CI/CD tool, or a set of database down-migration scripts.
Frequently Asked Questions
What is Rollback Plan in short?
A documented and tested procedure for reverting a specific release gracefully.
What is the most common failure mode?
Writing the rollback plan as a theoretical exercise but never testing it, only to discover during an incident that the down-migration script drops a critical table.
